, NEW JERSEY, ASSIGNOR TO onnnewoon TYPEWRITER COMPANY, OF YORK, N. Y., A CORPORATION OF DELAWARE.

TYPEWRITING MACHINE.

Application filed May 27, 1921.

To all who/n may concern:

Be it known that I, BURNHAM C. S'rioio Nor, a citizen of the United States, residing in Elizabeth, in the county of Union and a State of New Jersey, have invented certain new anduseful Improvements in Typewrit-- 511g Machines, of which the following is a specification.

This invention relates to noise-deadening 1o casings or hoods for typewriting machines, and is of the same general type disclosed in my co-pending application, Serial No. 429,617, filed December 10, 1920. The invention comprises, in combination with'a Ia typewriting machine, a. sound-deadening casing or hood for enclosing the noise-producing parts of the machine, while the keys and other parts of the machine used in its operation project from the casing or hood.

It is one feature of this invention to provide a die-cast hood which can be easily and cheaply produced.

Another feature of this invention is the construction of the hood in several parts, so that it may be knocked down or dis assembled to enable the parts to be packed within a minimum of space for convenience in shippin and which permits rapid and easy Tet-assembling. F or this purpose, the an hood comprises a cover part and a body part, tl'1e former being readily detachable from the latter, and the bodypart comprises, front,back and side members which are releasably connected to permit the disassembling of the body part. The cover and the various parts-of the body are separate die-castings and so formed that, when assembled, the hood presents a smooth, neatappearance. The cover is further provided with a transparent plate for permitting the machine within the casing to be viewed, and said plate is also releasably mounted to permit its withdrawal for separatepacking, or for replacement.

Other features and advantages will hereinafter appear.

In the accon'ipanying drawings,

part of the hood, the front plate being shown detached from the casing.

Figure f is a front elevation, partl tioned, of the assembled hood.

The Underwood standard typewriting machine comprises a main frame and an extension 11 of said frame, within which extension are positioned the usual banks of type-keys 9, the machine standing on feet 14, which are usually of rubber. The machine carries a letter-feed carriage 12, supported on a front rail (not shown) and a rear rail 13 on. the main frame, and is proided with a line-space handle 15, which projects forwardly and isbent downwardly for a purpose to be hereinafter described.

For enclosing the machine to deaden the sound produced in typewriting, there is provided a sound-deadening casing or hood which comprises, in general, a lower body part and an upper cover part 21, the body part comprising a front plate 22, end members 23, and a rearplate 24;, all of which are separate die-cast pieces. The end members 23 are provided with rear flanges 25, to the inside surfaces of which is fas- ,tened, preferably by screws 27, the back plate 24; by means of inwardly-extendinnmembers 26 (see Figures 1 and'3). By this arrangement, the outer surface of the back plate 24 is flush with the outer surfaces of flanges 25, and thus forms a smooth exterior without projections. The end members 23 are provided with horizontal extensions 30, over which the carriagetravels to the right and left, said extensions projecting laterally to either side beyond the limits of travel of the carriage. A rear wall 31 of the cover 21 is hingedly connected to-the back plate 2 1 by means of lugs 32 having perforations at their ends forming bearings, the lugs on the cover engaging between perforated lugs 33 on the back plate 24, the perforations of both sets of hugs forming: one long, continuous bearing for a releasable bolt 35, which. may be headed at one end and "pro vided with a nut (not shown) at the other end after it is passed through the lugs 32 and S3 to hold the cover to the body part. The cover is a one-piece diecasting and provided with a forwardly and downwardly sloping wall 39, having an opening behind which is seated a transparent plate 40, held in grooves il. formed by flanges 42 and l?) spaced from the rear surface of the core",

y sec- One-of said tianges,here shown asaflange -13, nay be made removable to facilitate withlrawal and replacement of the plate 10.

The cover part and the various members of "and: positioned by abutn'ients cast intogral with the back plate. To close the openings left between the machine and the easing at the rfront, the front plate 22 is at tached to endmembers 23 by means of bolts 46, passing through alignedv bearings 4:7 formed integral with the end members, and through bearings 48- formed integral with the front .plate22. and occupying the space between bearings 4:7 to form therewith one long, continuous bearing. The front plate 22 is provided with abutments aflto engage the frame 10, at the front.

The heights of front plate 22 and front wall 50 of thecover, are such that, when the cover 1s closed, a longitudinal slot is formed at the front through which various operating members, such as the line-space :handle 15,;project,-for which purpose the line-space handle isextended forwardly and bent downwardly, as previously described. It is necessary to close this slot to prevent sound from passing therethrough, and for this purpose there are provided cushion strips 51 and 52, which may be formed of loops or folds. of suitable material such as plush, felt, or soft leather, the two-ply margins of the cushion strips :beingfined to the inner surfaces,"adjacent the co-op crating "edges, of front plate. 22 and the front all of the cover.

The extensions 30 of the end members 23 terminate at the sides in horizontal ledges 55, forming supports upon which rest horizontal flanges 56' at the sides of the cover.

Layers of sound-deadening materialr59nre interposed between the ledges 55 and'fianges 56 at each side of the hood to prevent the transmission of sound through the sides of? the hood at the meeting edgesof the cover 5 portions for said overhanging side portions,

"and having flanges along the front and rear edges of both the upright and horizontal and body parts. i

A finger-piece 61 is provided at the lefthand end of the cover, by which the latter inn y be swung up to open the hood. In lmojcking down, or, in other-words, disassembling the device for shipping purposes, the cover part may be detached from the body part by withdrawing bolt 85; by removing flange 43, transparent plate 40 may be withdrawn and separately packed; and the body part may be disassembled'by withdrawing bolts 16 to release the front plate 22, and unscrewing back plate 20 from the end members 23. It is thus pos sible to pack the casing so tl1at- .it occupies "claim releasablyconnected 'to said body pgrmit the cover to be detached from the dy part, said walls being releasably 0on a minimum of space and may be conand that the means for fastening the front wall is of such construction to permit it to be readily and quickly detached from the casing, at will, while the latter is in its setup or assembled condition. 1

It will bcnnderstood that the casing may readily-be lined witlrany suitable sounddeadening material, such as felt.

The following claims are directed to inventi ve-organizations of body construction that are not disclosed in my co-pend ing appl ication, No. 381,259, filed May 14:, 1920.

Th s tllJlDllOEttlOll discloses improvements upon the sound-deadening inventions pat ented to John WValdheiin, No. 1, 199,709,

d uly 1, 1924, and upon theinventions shown in my applications, No. 429,617, filed December 16), i920, and No. 468,257, filed May "10, 15921, and in the application'ofAllard, No. 169,114, filed May '13, 1921, and in the application of John NValdheimyNo. 466,820, filed May 4:, 1921; the claims herein being limited to features ofbody construction not showminany ofsaid patent and applications. 1

Variations may scope of the invention, and portions ofthe improvements may be used without others.
